    Jboss EAP 6.2 java.lang.NoSuchMethodError: javax.validation.Configuration.getBootstrapConfiguration()Ljavax/validation/BootstrapConfiguration;

    Jboss Dev Newbie

      Hi all,

       

      We have lot of existing rest services developed using jersey and deployed in JBoss EAP 6.2.

      Now we are trying to incorporate Bean Validation Support (https://jersey.java.net/documentation/latest/bean-validation.html).

      Unfortunately we are getting following exception from server.
